Situations oftentimes arise in which one computing component sends a request to another computing component, such as one device sending a request to another device, one program sending a request to another program, and so forth. The recipient of the request may then send the request to yet another computing component. Some components, however, can receive a large number of requests. It can be difficult for components that receive large numbers of requests to manage all the requests they receive while at the same time providing the quality of service that they desire to provide, and further to manage these requests while not overloading other components to which they may send the requests.
